- 2 8-ounce red-skinned sweet potatoes (yams), peeled, sliced into 1/4-inch-thick rounds
 - 3 tablespoons frozen apple juice concentrate, thawed
 - 1/2 teaspoon ground cinnamon
 - 1/8 teaspoon ground cloves
 - 1 tablespoon butter, melted
 
- Preheat oven to 400°F. Place large baking sheet in oven to heat. Combine sweet potatoes, apple juice concentrate, cinnamon and cloves in medium bowl. Sprinkle generously with salt and pepper. Cut 2 sheets of foil, each about 20 inches long. Place 1 foil sheet on work surface. Spread half of sweet potatoes on 1 half of foil so that potato slices are not more than 2 deep. Drizzle with 1/2 tablespoon butter. Fold foil over, enclosing contents completely and crimping edges tightly to seal. Repeat with second foil sheet and remaining ingredients.
 - Place foil packets on heated baking sheet. Bake until sweet potatoes are tender, about 20 minutes. Remove from oven; let stand 5 minutes. Divide among 4 plates and serve.
